Background technology
Along with developing rapidly of car industry, automobile brake many employings drum brake, camshaft be its connect adjust arm with
The arrestment mechanism of brake shoe, during brake, brake chamber drives camshaft to rotate by regulating arm, two brakings
The roller of hoof rolls respectively on two curved surfaces of camshaft, thus drives two brake-shoes outwards to open with identical speed simultaneously
Open, make friction plate contact with brake drum and produce drag friction, reach to brake purpose.
Camshaft is parts in piston engine, and its effect is unlatching and the closed action controlling valve, though
So in four-stroke engine, the rotating speed of camshaft is half (rotating speed and the bent axle at two stroke engine convexity wheel shaft of bent axle
Identical), but generally its rotating speed is the highest, and needs to bear the biggest moment of torsion, therefore in design to camshaft by force
Requirement in terms of degree and support is the highest, and its material is usually superior alloy steel or steel alloy, owing to valve motion rule is related to
The power of one electromotor and service performance, therefore camshaft design in the design process of electromotor in occupation of highly important
Status.
At present, the general all structures of the cam power shaft that market is used are single, and use is inconvenient for, and impact makes normally
By effect, greatly reduce the efficiency of use.

And the 3rd cam lobe is fixedly connected with the first fixed block away from the side of the second cam lobe, described first fixed block away from
The side of the 3rd cam lobe is fixedly connected with the second fixed block by connecting plate, and the second fixed block is away from the one of connecting plate
Side is fixedly connected with the second connecting shaft, and described second connecting shaft is fixedly connected with extension away from one end of the second fixed block, and
And extension is fixedly connected with outfan away from the side of the second connecting shaft.
Preferably, the junction between described 3rd cam lobe and the first fixed block is curved.
Preferably, described input section is away from the inclined shape in side of the first connecting shaft.
Preferably, the junction between described first fixed block and connecting plate is curved.
Preferably, the junction between described first connecting shaft and the first cam lobe is curved.
(3) beneficial effect
This utility model provides a kind of cam power shaft.Possess following beneficial effect:
(1), this cam power shaft, by input section, the first connecting shaft, the first cam lobe, the second cam lobe, the 3rd
Cam lobe, the first fixed block, connecting plate, the second fixed block, the second connecting shaft, cooperation between extension and outfan are even
Connect, solve the general situation that all structure is single of the cam power shaft used in the market, preferably facilitate use, protect
Demonstrate,prove normal using effect, improve the efficiency of use.
(2), this cam power shaft, curved by the junction between the 3rd cam lobe and the first fixed block, first
Junction between fixed block and connecting plate is curved, junction between the first connecting shaft and the first cam lobe is curved,
Improve smooth degree, it is possible to quickly slip over, preferably improve the efficiency of work.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
This utility model embodiment provides a kind of cam power shaft, as shown in Figure 1-2, including input section 1, input section 1
One end is fixedly connected with the first connecting shaft 2, and input section 1 is away from the inclined shape in side of the first connecting shaft 2, and the first connecting shaft
2 are fixedly connected with the first cam lobe 3, the company between the first connecting shaft 2 and the first cam lobe 3 away from the one end inputting section 1
